Developmental Milestones


Your child's doctor or nurse will measure your child's height and weight regularly. Your child's head size will also be measured during the first 2 years of life. Keep track of the child's growth in the growth record. These measurements will help you and your doctor know whether your child is growing properly.


Children develop at different rates. This table shows the ages by which most young children develop certain abilities. It is normal for a child to do some of these things later than the ages noted here. If your child does not do many of these things at the ages given or if you have questions about his or her development, talk with your child's doctor or nurses.
